Detailed description of the invention
Now describe better embodiment of the present invention in detail in conjunction with Figure of description.
Composition graphs 1, Fig. 2 and Fig. 3, a kind of amenities device for recovering powder, comprise drug sundries product line 1, device for recovering powder and dust deposited case 9, arrange some forced draft fans 2 along drug sundries product line 1 interval, device for recovering powder is arranged by left box body 3, middle casing 4 and right case 5 and assembles; The air outlet of forced draft fans 2 is all communicated with left box body 1; Dust exhaust apparatus 28 is provided with in middle casing, the dust suction end 29 of dust exhaust apparatus 28 to stretch in right case 5 and extends between adjacent two filters 24, top outside middle casing 4 is provided with dust absorption fan 7, and dust absorption fan 7 one end is connected with dust exhaust apparatus 28, and dust absorption fan 7 other end is connected with dust deposited case 9; In right case 5, the sheathed several layers of filter 24(of level are as shown in Figure 2), the right side of filter 24 is provided with air outlet 13, realizes filter 24 inside be in communication with the outside by air outlet 13.
Composition graphs 1, Fig. 2 and Fig. 3, a kind of amenities dust recovery method: first, the dust that on drug sundries product line 1, forced draft fans 2 air outlet is discharged enters in the left box body 3 of device for recovering powder, casing 4 in passing through, enter in right case 5, be dispersed in the space between some layers of filter 24; Then, the air after filter 24 filters flows out from the air outlet 13 of filter 24 right-hand member, and meanwhile, dust is attracted to the surface of each filter 24; Start dust absorption fan 7, dust enters dust exhaust apparatus 28 from dust exhaust apparatus dust suction end 29 under the suction of dust absorption fan 7, then through dust absorption fan 7, is sent in dust deposited case 9.
The advantage of this amenities device for recovering powder is: (1) adopts multi-layer filtrating equipment 24, considerably increases filter table area, thus, reduce the filtration yield of dust in unit are, make filter 24 not easily dirty and blocking, long service life, has saved cost; (2) air after filtering flows out from air outlet 13, and reduce the inside and outside differential pressure in device for recovering powder, the fine hair not in easy damaged dust, improves the recovery utilization rate of fine hair; (3) because the dust reclaimed is except fine hair, also containing impurity such as dusts, by the dust collection after reclaiming in dust deposited case 9, enter drug sundries product line 1 again after carrying out further removal of impurities, in can avoiding directly utilizing, impurity is on the impact of follow-up end product quality.
Although above-mentioned amenities device for recovering powder overcomes the defect of prior art, in this amenities device for recovering powder, the cross-sectional area of sweep-up pipe suction port 16 is limited, and dust suction operation exists dead angle.
On the basis of above-mentioned amenities device for recovering powder, do further improvement: a central shaft 10 is set in middle casing 4, filter 24 is set in outside central shaft 10, and the left end of central shaft 10 is fixedly connected with filter 24, right-hand member stretches out outside right case 5 through the right side wall 12 of right case 5; Central shaft 10 is driven by the reductor 14 be arranged at outside right case 5 and rotates; The central shaft 10 stretched out outside right case 5 is provided with reciprocating drive unit 26; Filter 24 is spaced apart with sweep-up pipe 8.
In the course of the work, dust is attracted to the surface of each filter 24; Reductor 14 drives central shaft 10 to move in a circle, thus, drive girder 6 and aspiration channel 8 to move in a circle; Reciprocating drive unit 26 drives central shaft 10 to do bilateral reciprocation, drives girder 6 and aspiration channel 8 to do bilateral reciprocation; Therefore, sweep-up pipe inlet scoop 16 is moved along spiral routes on the surface of filter 24 and is carried out dust suction, and when sweep-up pipe 8 runs left and to the right, route is anti-raw overlapping, thus, realize the dust suction on aspiration channel 8 pairs of each positions of filter 24.
Dust exhaust apparatus is made up of with the sweep-up pipe 8 be arranged on girder 6 girder 6 of inner hollow, the left end of sweep-up pipe 8 is connected with girder 6, sweep-up pipe 8 right-hand member extends between adjacent two filters 24, the air outlet of girder 6 is connected with dust absorption fan 7 by pipeline, realizes the recovery to the dust being attached to filter 24 surface.
As shown in Figures 2 and 3, the inner barrel that described filter 24 is surrounded around central shaft 10 respectively by attached dirt net 11 and weighing apparatus pressing plate 15 and outer cylinder body form, the left end of weighing apparatus pressing plate 15 is downward-sloping, the left end of attached dirt net 11 and weighing apparatus pressing plate 15 is connected to each other, the right-hand member of attached dirt net 11 and weighing apparatus pressing plate 15 surrounds air outlet 13, and the suction port 16 of sweep-up pipe 8 is all towards corresponding attached dirt net 11.Because the flow direction of air-flow in device for recovering powder is from left to right, when being with the air-flow of dust to enter between adjacent filter 24, the weighing apparatus pressing plate 15 of the filter 24 of central shaft side can change the flow direction of air-flow.
Attached dirt net 11 outer wrapping flannelette.Flannelette has gas permeability, is filtered dust by flannelette, and wherein flannelette preferably adopts pleuche.
As shown in Figure 4, central shaft 10 is respectively equipped with A fixed hub 17 and B fixed hub 18, belt pulley 27 is provided with between A fixed hub 17 and B fixed hub 18, reductor 14 is by belt pulley 27 transmission central shaft 10, the end of belt pulley 27 side of A fixed hub 17 and B fixed hub 18 is equipped with outward extending A flange 19 and B flange 20, be fixedly connected with by Limit screw 28 between A flange 19 and B flange 20, can prevent dust deposit on the center shaft 10 or in shaft clearance, affect dust and reclaim normally carrying out of operation.
As shown in Figure 4, reciprocating drive unit 26 comprises positive/negative thread cover 21 and commutation slide block 22, and positive/negative thread cover 21 is locked on the center shaft 10, and B fixed hub 18 is sleeved on outside positive/negative thread cover 21, and B fixed hub 18 is provided with commutation slide block 22.When central shaft 10 moves in a circle, thread tracks on positive/negative thread cover 21 is also being slided by commutation slide block 22, and then the outwards movement of band central shaft 10, when arriving the left part of thread bush 21, commutation slide block 22 turn threads track automatically, and then band central shaft 10 moves in the opposite direction, the like, thus realize the left and right reciprocally swinging of girder 6.
As shown in Figure 4, the right axle head of B fixed hub 18 is provided with the cylindrical cavity body 23 of horizontal positioned, and positive/negative thread axle sleeve 21 and central shaft 10 can slide in cylindrical cavity body 23.Not by the interference of external substance when this cavity body 23 can ensure that positive/negative thread cover 21 and central shaft 10 outwards screw out, and also can prevent dust deposit on reciprocating drive unit, affect its normal operation.
Two sweep-up pipes 8 one between adjacent two filters 24 are long, one short, and the length difference of two aspiration channels 8 is less than the length of 1/2 screen pack.The stroke of the bilateral reciprocation of central shaft can be shortened like this, and increase the dust suction number of times in the middle of attached dirt net.
As shown in Figure 5, ramp type is arranged in the lower left corner of left box body 3.
As shown in Figure 1 and Figure 5, in specific implementation process, respectively place a laying dust bag 25 in dust deposited case 9 middle left and right both sides, the dust entering dust deposited case 9 is deposited in laying dust bag under self gravitation effect.The design of laying dust bag facilitates the transfer of workman to dust in dust deposited case, and changing laying dust bag can carry out when not stopping normal work.
The present invention is mainly used in during amenities produces, and also can be used for other field, the present invention is that a kind of cost is low, and the high device for recovering powder of dust recovery utilization rate and recovery method.
